Abstract
For transfer of memory contents between an extended buffer memory and one of a first and a second main memory and of a peripheral storage device connected to an input-output processor, a transfer controlling arrangement can simultaneously receive transfer requests produced by a central processor, an arithmetic processor, and the input-output processor and can control the transfer requests. The transfer controlling arrangement comprises an extended buffer memory transfer controller connected to the central and the input-output processors through a first transfer controller, to the arithmetic processor through a second transfer controller, and to the extended buffer memory.
